Product Description
The EH2.5 SMT wire‑to‑board connector provides a compact, reliable cable‑to‑PCB interface for low‑voltage electronics while supporting fully automated assembly. The series combines polarized, shrouded housings and crimp terminals with vertical or right‑angle surface‑mount headers engineered for lead‑free reflow.
Key features
- 2.5 mm pitch with shrouded, polarized keying to prevent mis‑mating
- Optional friction/self‑lock to improve retention under vibration and handling
- SMT headers in vertical (top‑entry) and right‑angle (side‑entry) orientations
- High‑temperature header resin for lead‑free reflow; coplanarity controlled; optional metal hold‑downs
- Space‑saving low profile; ideal for automated pick‑and‑place with peelable pick‑up caps
- Complete BOM: housings, crimp terminals, SMT headers; wire harness customization available
- Drawings, 3D models, PCB footprints, and assembly guidance provided
Typical specifications (vary by supplier/series)
- Circuits: 2–12 pins
- Rated current: up to 3 A per pin (dependent on wire gauge and temperature rise)
- Rated voltage: up to 250 V AC/DC
- Contact resistance: ≤20 mΩ (typical)
- Insulation resistance: ≥1000 MΩ (typical)
- Dielectric withstand: 1000–1500 VAC for 1 minute (typical)
- Operating temperature: −25 °C to +85 °C
- Mating cycles: ≥50 (typical)
Materials and plating
- Contacts: brass/phosphor bronze, tin plated; optional nickel underplate with selective gold
- Housing: PA66 or PBT, natural/white; optional UL94 V‑0 flame rating
- SMT headers: PA9T/LCP high‑temperature bodies; solder tails with matte tin; optional solder tabs for mechanical strength
Cable side and assembly
- Crimp terminals for AWG28–22 (≈0.08–0.34 mm²)
- Supports manual crimping and automated applicators; pre‑crimped leads and pull tests available
- Harness customization: core count, gauge, length, color, labels, heat‑shrink, sleeving/overmold
- SMT packaging: tape‑and‑reel with pick‑up caps; reflow‑compatible per lead‑free profiles
PCB and process notes
- Recommended pad layouts and stencil apertures available
- Coplanarity and reflow profile guidance provided; cleaning and inspection recommendations included
Compliance
- RoHS and REACH compliant
- Optional UL94 V‑0 housing and halogen‑free variants
- Incoming inspection and test reports on request
Typical applications
- LED lighting and drivers
- Consumer electronics and IoT nodes
- Instruments, sensors, control boards
- Small appliances, battery packs, low‑voltage motor control
